ABSTRACT:
The present invention relates to a rubber dam frame comprised of two vertical side leg members that are connected by a single uninterrupted lower horizontal member and both a left and right upper horizontal member. The frame has a downwardly curved concave nasal deflection element positioned between the left and right upper horizontal members for increasing patient comfort along with a mechanism for attaching and deflecting excess rubber dam material downward to prevent the material from obstructing the nose and the breathing of the patient. The rubber dam membrane is attached to the rubber dam frame through the use of attachment nibs that face outward from the perimeter of the frame and secure the rubber dam membrane to the frame and allow for improved retraction and stability.
